EZ-RocketX-Racer

We have continued the technological development of rocket engines, building and enhancing many designs from 15 lb thrust up to 7,500 lbf.XCOR’s engines burn a variety of non-toxic fuels, including kerosene, hydrogen, methane, ethane, propane, alcohol and kerosene using oxidizers such as liquid oxygen and nitrous oxide.

Our 5K18 engines for the Lynx Spacecraft produce 2900 lbf thrust while burning a mixture of liquid oxygen and kerosene. It has design and performance characteristics similar to the X-Racer engine.
